All Keyboard Test Tools
Free tools running in your browser with nothing to install. They fall into four groups: tests built around a specific keyboard layout, hardware diagnostics for faults like chatter and ghosting, tests for one individual key or section, and tests for typing and performance.
If you are here because something is wrong, the fastest route is the symptom table below — it maps the complaint you actually have to the tool that answers it. If you are not sure what is wrong, start with the main keyboard test. Note which events arrive and which do not, then use the relevant focused workflow.
Find the right tool by symptom
| What you are seeing | Tool that answers it |
|---|---|
| A key does nothing when I press it | Keyboard Test |
| One key types two letters | Double Typing Test |
| A key repeats without being held | Stuck Key Test |
| Everything types in capitals | Stuck Key Test |
| Keys drop out when I hold several | Ghosting Test |
| My character will not move diagonally | Arrow Keys Test |
| The numpad types arrows instead of numbers | Numpad Test |
| F1 to F12 do the wrong thing | Function Key Test |
| My Chromebook has no Delete key | Chromebook Keyboard Test |
| I want to know how many keys my board handles at once | N-Key Rollover Test |
| I want to know how fast I type | WPM Test |
| I want to try synthesized typing sounds | Keyboard Sound Test |

Keyboard Test
Press each physical key and compare the layout, tested count, held keys and event details. Unobserved keys need a follow-up check in another browser or application.
Keyboard Layout Tests
Test a specific keyboard layout
Windows Keyboard Test
Check PC keyboard keys on a Windows layout
Mac Keyboard Test
Check MacBook and Apple Magic Keyboard keys
Laptop Keyboard Test
Check built-in laptop keys and Fn layers
Chromebook Keyboard Test
Test the Search key and ChromeOS top row
Mechanical Keyboard Test
Check switch registration and missed presses
Gaming Keyboard Test
Test WASD, sprint and jump keys together
Hardware Diagnostics
Find faults and multi-key problems
Ghosting Test
Check anti-ghosting combinations for missing keys
N-Key Rollover Test
Compare 2KRO, 6KRO and NKRO key combinations
Double Typing Test
Check keyboard chatter and double typing
Stuck Key Test
Find keys that stick or repeat on their own
Keyboard Timing & Latency
Measure key press and release timing
Individual Key Tests
Test one key or one section
Typing & Performance
Measure typing speed and switch sound
How these tools fit together
Device layouts make physical positions easier to compare. Diagnostic tools investigate one symptom at a time: rapid repeated presses, a missing release or a failed combination. Browser events cannot identify every hardware fault.
Start with individual keys, then test the exact combinations you use. Compare the ghosting test with the rollover counter to distinguish missing events from an observed simultaneous-key count.
Typing and WPM tools report practice scores. Sound profiles are synthesized effects, not recordings or measurements of your keyboard. Read how we test for the measurement definitions and browser limits.
Gaming Tests
Check gaming key combinations, then compare missing combinations, simultaneous key counts and browser timing intervals.
Troubleshooting
Follow the guides for keys not working, double typing, wrong letters, input lag or inspecting a used keyboard.
Frequently asked questions
Which keyboard test should I start with?
Start with the main keyboard test on the homepage. It checks every key on a full layout in one pass, which tells you whether the problem is one key or many. Only then move to a specialised test — the symptom table on this page maps each complaint to the right tool.
Are all of these tools free?
Yes. There is no account, no install, no extension and no trial. Test calculations run locally. Keyboardtest’s diagnostic code does not upload key events. Separate analytics, advertising and optional translation are described in the privacy policy.
Do these tests work on a laptop, Mac or Chromebook?
All of them work on any device with a physical keyboard. Several are built around a specific layout — the Mac, laptop and Chromebook tests draw the real key arrangement for those machines, which matters because a generic layout mislabels keys like the Chromebook Search key.
Can a browser test find a hardware fault?
It shows whether a tested key reaches this browser in the current session. Compare other apps, browsers and connections before deciding on repair. It cannot tell you whether the cause is the switch, the ribbon cable or a remapping tool. Where that distinction matters, each tool says so on its own page.
Do you record what I type?
Keyboardtest’s diagnostic code keeps key events in page memory and does not upload them. Preferences may be saved locally. See the privacy policy for separate third-party services.
What is the difference between the typing test and the WPM test?
The typing test focuses on accuracy and shows your errors as you make them. The WPM test focuses on speed, reports net alongside raw words per minute so you can see what your errors cost, and explains how the score is calculated.
